I see the author links to his youtube playlist for his CMU Databases class. https://www.youtube.com/playlist?list=PLSE8ODhjZXjaKScG3l0nuOiDTTqpfnWFf https://www.youtube.com/playlist?list=PLSE8ODhjZXjaKScG3l0nu... Are there any good recommendations for a lecture or series of lectures that go over Databases from a theoretical perspective but also do a practical survey of the various DB systems and technologies out there?
